SODIUM POLYNAPHTHALENESULFONATE

Safety grade: A

This is a synthetic chemical compound derived from naphthalene (a component of coal tar) that acts as a stabilizer and thickener in cosmetic formulations. It helps keep products well-mixed and gives them the desired texture.

It stabilizes emulsions to prevent separation, thickens products into gels, helps dissolve other ingredients evenly, and reduces surface tension to improve product performance and shelf life.
